GRE Sample Test 3 Quantitative Reasoning 1

Plug in values: Let a = 4, b = 2, and k = 1. In this case, Quantity A = $\frac{4}{2}$ = 2 and Quantity B = $\frac{5}{3}$. With these values, Quantity A is greater.Now, choose new values: Let a = 100, b = 2, and k = 1. In this case, Quantity A = $\frac{100}{2}$ = 50 and Quantity B = $\frac{101}{3}$. Quantity A is still greater.
